Bob, I checked the 5.8.2a distribution and both gdcfil and gdbiint were in the linux binary. The changes in GEMPAK since 5.8.1 now allow GEMPAK to do computations on grids with differing navigations, so at some point, the need to interpolate grids may not be necessary. That aside, there shouldn't be anything in the 5.8.3 grid files that prevents reading with your 5.7.3, unless they have increased their maximum grid size to larger than what you have. I've always tried to keep the Unidata release ahead of the NCEP version for that reason - our LLMXGD has been 400,000 for several years, and NCEP's is 275,000. I have a preliminary Linux binary of 5.8.3a ready for our workshops next week that you can download...but the LLMXGD is the same as it has been. If you want to send me any grid file from SPC, or some more information about whether gdbiint is finding the grid in the source file, and not writing the output, or failing before then etc, I'd be happy to look int this more. Since you indicate that you had been sucessful with previous grids from SPC with that same 5.7.3 binary you have, I was leaning to wondering if SPC in particular has redefined their maximum grid size (I know that AWC produces some 1.6 million point grids!).
